PHOTOSHOP CC: Quick mask mode not working on Windows

My Photopshop CC for windows does not open quick mask mode when I try any of these three (Select / edit in quick mask, or hitting Q on the keyboard, or clicking the washing machine Icon) Instead it goes into and Alpha/8 or 16 mode. And I am not able to paint any masks? What an I missing? I have the latest software (last week) and use the windows version
